deb: install zsh completions to /usr/share/zsh/vendor-completions This location is used by debian (and ubuntu) to store completions provided by other deb packages.

commands: rename clone --uncompressed to --stream and document --uncompressed isn't a very good name and its description in the help documentation isn't very useful. We refer to this concept as "stream clones" in a number of places. I think it makes sense to change the user-facing argument to use the mode --stream. So this commit does that. We keep --uncompressed around for backwards compatibility. While we're here, we overhaul the help docs for streaming clones to be somewhat useful. All tests have been updated to reflect the new preferred --stream argument. A test for backwards compatibility of --uncompressed has been added. .. bc:: `hg clone --stream` should now be used instead of --uncompressed. --uncompressed is marked as deprecated and is an alias for --stream. There is no schedule for elimination of --uncompressed. Differential Revision: https://phab.mercurial-scm.org/D864

hgweb: add HTML elements to control whitespace settings for annotate Building on top of the new URL query string arguments to control whitespace settings for annotate, this commit adds HTML checkboxes reflecting the values of these arguments to the paper and gitweb themes. The actual diff settings are now exported to the templating layer. The HTML templates add these as data-* attributes so they are accessible to the DOM. A new <form> with various <input> elements is added. The <form> is initially hidden via CSS. A shared JavaScript function (which runs after the <form> has been rendered but before the annotate HTML (because annotate HTML could take a while to load and we want the form to render quickly) takes care of setting the checked state of each box from the data-* attributes. It also registers an event handler to modify the URL and refresh the page whenever the checkbox state is changed. I'm using the URLSearchParams interface to perform URL manipulation. https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams tells me this may not be supported on older web browsers. Yes, apparently the web API didn't have a standard API to parse and format query strings until recently. Hence the check for the presence of this feature in the JavaScript. If the browser doesn't support the feature, the <form> will remain hidden and behavior will like it currently is. We could polyfill this feature or implement our own query string parsing. But I'm lazy and this could be done as a follow-up if people miss it. We could certainly expand this feature to support more diff options (such as lines of context). That's why the potentially reusable code is stored in a reusable place. It is also certainly possible to add diff controls to other pages that display diffs. But since Mozillians are making noise about controlling which revisions annotate shows, I figured I'd start there. .. feature:: Control whitespace settings for annotation on hgweb /annotate URLs on hgweb now accept query string arguments to influence how whitespace changes impact results. The arguments "ignorews," "ignorewsamount," "ignorewseol," and "ignoreblanklines" now have the same meaning as their [annotate] config section counterparts. Any provided setting overrides the server default. HTML checkboxes have been added to the paper and gitweb themes to expose current whitespace settings and to easily modify the current view. Differential Revision: https://phab.mercurial-scm.org/D850

hgweb: query string arguments to control whitespace for annotate This feature should hopefully be pretty straightforward. We simply examine some query string arguments to feed into the diff options. The function to obtain the diff options has been factored into its own generic function to facilitate an upcoming change to the HTML interface and to enable diff settings to be controlled via the same query string arguments on other web commands. The test output for "ignoreblanklines" didn't change. I'm not sure why. Our test coverage for --ignore-blank-lines isn't great and I can't figure out how to make this diff setting do anything meaningful. On a very brief examination of the code, it is possible the setting doesn't work because it is operating at the line level and blank lines detection needs to examine multiple lines. But I'm not an expert in this code, so I'm not sure. Differential Revision: https://phab.mercurial-scm.org/D849

copytrace: use ctx.mutable() instead of adhoc constant of non-public phases

exchange: fix test for remote support of binary phases If the remote do not support phases, the "get" call will return None. We change that default return to empty tuple to fix the membership testing. This was a bug in the initial series. Thanks to yuja for catching this.

exchange: perform stream clone with clone bundle with --uncompressed Previously, `hg clone --uncompressed` would always clone from the origin server, even if a streaming clone bundle were available. With this change, we invoke the clone bundle mechanism before the stream clone mechanism, giving clone bundles the opportunity to handle --uncompressed (which is mapped to pullop.streamclonepreferred). The clone bundle filtering code now filters out entries that aren't stream clones when a stream clone is requested. If a stream clone clone bundle entry is present, it will be used. Otherwise, the client will fall back to a server-based streaming clone. .. feature:: `hg clone --uncompressed` uses clone bundles when possible Differential Revision: https://phab.mercurial-scm.org/D833

config: use copy-on-write to improve copy performance Previously, chg's `verify` call could take 30+ms loading and checking new config files. With one socket redirection, that adds up to around 70ms, which is a lot for fast commands (ex. `bookmark --hidden`). When investigating closer, A lot of time was spent on actually spent on ui copying, which is mainly about `config.config` and `dict` copying. This patch makes that 20x faster by adopting copy-on-write. The copy-on-write is performed at config section level. Before: In [1]: %timeit ui.copy() 100 loops, best of 3: 2.32 ms per loop After: In [1]: %timeit ui.copy() 10000 loops, best of 3: 128 us per loop 2ms may look not that bad, but it adds up pretty quickly with multiple calls. A typical chg run may call it 4 times, which is about 10ms. Differential Revision: https://phab.mercurial-scm.org/D808

py3: return False early while checking whether None is a key in lazymanifest In this patch we returns False early if we are trying to check whether None is a key in lazymanifest. The reason I added a diff is that on Python 3, it goes into the lazy manifest code an returns a TypeError. I checked with Durham that whether None can be a possible key in lazymanifest and he said "no". So it's safe to have this if statement. This fixes `hg merge` on Python 3.
